Needle for stereographic embroidery

ABSTRACT

A needle for stereographic embroidery is mainly composed of a main body which is provided with a tapered drilling part, shaped as a cone for drilling through a cloth easily, and a fixing pivot, at its other side, having a thread for screwing together with a embroidering machine. The tapered drilling part, being shaped as a cone, can drill through a hole of the cloth to squeeze outwards the longitudinal and the latitudinal yarns around the hole without damaging to them, achieving the previous drilling action in the stereographic embroidery and keeping the cloth as a whole. Because the drilling action does not damage to any yarns but squeezes them outwards, it provides a more complete basis for embroidering on the yarns to obtain a more vivid and stereographic picture.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a needle for stereographic embroidery, particularly to one that carries out the previous drilling work without breaking down yarns of a cloth to keep the cloth as a whole, enabling the needle to avoid the defects, breaking down the yarns and reducing the strength of the cloth, the conventional has. Since the drilling action in the present invention does not damage the cloth as the conventional does, it provides a more complete basis for embroidering on the yarns with a more vivid and stereographic picture. And, due to a drilling circumference of a tapered drilling part is shaped as a cone, it is to endure an even force, reducing abrasion greatly.

2. Description of the Prior Art

A conventional needle for embroidering, as shown in FIGS. 1 and 2, is mainly composed of a main body 1 provided with a tapered drilling part 2 and a fixing pivot 3. The tapered drilling part 2 is formed as a quadrilateral pyramid provided with four arêtes 22 and a drilling tip 21. Because the arêtes 22 is rather sharp, they may cut off the longitudinal and the latitudinal yarns of the cloth while drilling through the cloth for embroidering, causing damage to the structure of the cloth losing its original strength. And, the arêtes 22 after numerous drillings are to diminish their sharpness, so that they must be replaced often.

In addition, a combined method of making stereographic texture and embroidering, patent No. 90118513 authorized by Taiwanese Patent Office, uses a reverse U-shaped “reversed-fork needle” to hook the yarn outwards. The U-shaped “reversed-fork needle” is form of very tenuous so that it is to deform easily after long-term use. Therefore, if lots of the U-shaped “reversed-fork needles” are used in a huge embroidering machine, it would take a lot of time to replace and correct them, causing a low efficiency and a higher cost.

Therefore, this invention has been studied to improve the structural defects in the conventional.

SUMMARY OF THE INVENTION

The prime object of this invention is to offer a needle that does not break down the longitudinal and the latitudinal yarns in a cloth, keeping the cloth as a whole.

The main characteristics of the invention are:

1. A drilling tip in the present invention is form as a flat circle that is to pass through a hole of the cloth first. Then, a drilling circumference is to squeeze outwards the yarns around it.

2. The drilling circumference can squeeze outwards the yarns around it to provide a good basis for embroidering, able to obtain a more stereographic and aesthetic picture on the cloth.

3. The drilling circumference has a smooth coned surface so that it is to endure an even force while drilling, minimizing the abrasion.

4. The drilling circumference can be varied into other shapes as long as it maintains smoothly as a cone and does not break down the yarns of the cloth.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

As shown in FIGS. 3 and 4, a preferred embodiment of a needle for stereographic embroidery in the present invention is mainly composed of a main body 1 which is provided with a tapered drilling part 2 and a fixing pivot 3. The fixing pivot 3 is provided with a thread 31 to screw with an embroidering machine. The tapered drilling part 2 is shaped as a smooth cone having a drilling tip 21 and a drilling circumference 22.

In using, when the needle in the invention is to drill through a cloth 4, the drilling tip 21 will first pass through a hole 41 in the cloth 4 and, then, the 22 is to squeeze yarns 42 as shown in FIG. 5, making the yarns 42 become denser. Next, while the needle in the invention moves away from the cloth 4, the hole 41 is kept as shown in FIG. 6. By the same time, a wanted picture can be embroidered on the denser yarns 42, which will make the embroidered picture be more vivid and stereographic.

Furthermore, the tapered drilling part 2 is not merely shaped as a cone, it can be designed with a variety as long as the longitudinal and the latitudinal yarns are not broken down. By experiments, the tapered drilling part 2 can be instead shaped as an ellipse, a smooth triangle pyramid, a smooth quadrilateral pyramid or a smooth hexagonal pyramid etc. The drilling circumference 22 is also able to be designed as a shape of a wave or a ladder, as shown in FIG. 8, as long as it can keep the tapered drilling part 2 being forced even to reduce abrasion and not harmful to the longitudinal and the latitudinal yarns.

While the preferred embodiment of the invention has been described above, it will be recognized and understood that various modifications may be made therein and the appended claims are intended to cover all such modifications that may fall within the spirit and scope of the invention.
